A layout requires that a navigation menu be hidden off-screen and only appear when triggered on smaller screens to save space. What approach could be used to transition the menu on and off-screen responsively?
- display: none;
- opacity: 0;
- transform: translateX(-100%);
- visibility: hidden;
To hide a navigation menu off-screen and make it appear on smaller screens, you can use transform: translateX(-100%) to move it off-screen and then transition it on-screen when triggered. This approach ensures a smooth and responsive transition.

How does the use of CSS media queries enhance accessibility for users with specific needs, such as those requiring high contrast or large text?
- By adapting the layout based on device characteristics
- By allowing users to disable CSS for a simplified layout
- By enabling users to switch between dark and light modes

In a scenario where an element should remain fixed at the top of the viewport upon scrolling, but only after the user scrolls past a certain point, which CSS positioning scheme would be most appropriate?
- position: absolute; top: 0;
- position: fixed; top: 0;
- position: relative; top: 100px;
- position: sticky; top: 100px;
The position: sticky; property is ideal for creating an element fixed at the top after a certain scroll point. It combines features of both fixed and relative positioning, providing a seamless effect as the user scrolls.
How do you set a gradient that transitions from left to right?
